Total kidney volume (TKV) is a parameter used in both treatment decision and follow-up in autosomal dominant polycystic kidney disease (ADPKD) patients. The objective of this study was to evaluate intra- and interobserver agreement of the ellipsoid formula (EF) and manual boundary tracing method (MBTM) used in TKV measurement of ADPKD patients across different levels of experience radiologists. Additionally, the study aimed to evaluate the correlation between the EF and MBTM, which is considered the gold standard for TKV. ⋯ Both the EF and MBTM methods used for the measurement of TKV provided excellent intra- and interobserver reproducibility. The EF is as accurate and precise as the MBTM. It may therefore be preferred in radiology departments with heavy workload, as it is a reliable method for rapid and easy assessment, independent of experience.

Management of asymptomatic kidney stones is an ongoing debate with follow-up and treatment guidelines based on low-level evidence. Our aim was to evaluate current management of asymptomatic urinary stones. ⋯ Current treatment and follow-up patterns of asymptomatic urinary stones are in agreement with international guidelines on symptomatic stones.In most of the urolithiasis situations urologists chose a conservative approach for their patients compared to what they would prefer for themselves. Conversely, urologists, in the scenarios as "the patient", would like to have a more frequent follow-up schedule for their stones compared to how they would follow-up their patients.

The objective of this study was to demonstrate the commonalities and distinctions between patients with seronegative and seropositive primary Sjögren's syndrome (pSS). ⋯ While hematological, renal, pulmonary, and neurological involvements are observed with similar frequency in both seronegative and seropositive pSS patients, the presence of extraarticular manifestations was more common in seropositive patients. Additionally, there was a relationship between extraarticular involvement and low C4 levels.

Uterine leiomyosarcomas (uLMS) are extremely rare high-grade tumors with a poor prognosis. Their etiopathogenesis remains largely unknown. The uterus is the most frequent site for LMS. uLMS and uterine leiomyoma (uLM) must frequently be differentiated in patients with a uterine mass. Nicotinamide N-methyltransferase (NNMT), a cytoplasmic protein, is involved in the progression and spread of a variety of cancer types. The expression of NNMT in a mesenchymal malignancy was not examined previously. This study represents the first investigation into NNMT expression in uLMS, uLM and benign uterine myometrium and correlates NNMT overexpression with worse prognosis in uLMS. ⋯ NNMT can aid in the preoperative differentiation of uLMS and uLM. The consequences of NNMT overexpression, such as the activation and inactivation of oncoproteins and tumor suppressor proteins, respectively, as well as the enrichment of the cancer stem cell population, overlap with the major mechanisms responsible for poor prognosis in mesenchymal tumors. NNMT may be investigated further in the context of antitumor treatment in patients with mesenchymal malignancies.

Glioblastoma is one of the most aggressive tumours, resistant to all applied therapy regiments and prone to relapse. Median survival rates are therefore only expressed as months. STING agonists are immunomodulatory molecules that activate type I interferon expression, making them potentially useful in regulating the tumour microenvironment. Since PTEN serves as a critical phosphatase in activating interferon-regulating transcription factors and is frequently mutated in glioblastoma cells, this study aimed to investigate STING activation in glioblastoma cell lines, examining whether they harbour the PTEN protein or not.°. ⋯ Our data offers new evidence suggesting that STING agonists can effectively be used to increase temozolomide response in the presence of PTEN protein. Therefore, increased GBM therapy success rates can be achieved by employing the PTEN expression status as a predictive biomarker before treating patients with a chemotherapeutic agent in combination with STING agonist.
